SPECIFICATION formingpart of Letters Patent No. 275,355, dated April 10,1883.

Application filed September 22, 1882.

(No model.)

-materials are pulverized by power-operated stamp-rods combined withmortars.

In the accompanying drawings, Figure 1, Sheet 1, isa general view ofapparatus with which my invention is connected; Fig. 2, a verticalsection of the mortar and appliances connected therewith; Fig. 3, Sheet2, a plan view, partly in section, of Fig. 2; and Fig. 4, a sectionalplan on the line 1 2, Fig. 2.

Referring to Fig. 1, A is a substantial frame, carrying at the top twocylinders, B, one only being shown in the drawings. The pistons of thesetwo cylinders are connected to stamprods 0, the lower ends of whichoperate on minerals or other material to be pulverized in the mortars L,which are supported on a foundation separate from that of the frame.Sometimes I use a single steam-cylinder with one mortar and onestamp-rod.

A description of the steam-stamp will not be necessary, as my inventionrelates to the stamp and mortar L and its connections, and is notrestricted to any specific mechanism for operating the stamp. On the topof this mortar is a chamber, L, to which air is admitted freely, asexplained hereinafter. This chamber communicates through a pipe, M, witha receiver, M, and the latter through a pipe, N, with theexhaust-opening of a fan-blower, N, the discharge-opening of the lattercommunicating through a pipe, P, with a second receiver, P. The airrushing through the chamber of the mortar carries with it thefinely-pulverized material through the pipe M, the heavier and coarserparticles falling'to the bottom of the receiver M and the finerparticles passing through the pipe N, blower N, and pipe Pinto thereceiver 1?.

It should be understood that I do not claim in this application thisexhausting mechanism, which, together with the steam stamp and frame,have been briefly described, so as to betterexplain the inventionillustrated in Figs. 2, 3, and 4..

The mortar L is a substantial casting containing the anvil Q, which islet into the bottom of the mortar, and is confined thereto by theannular tapering lining Q, and a substantial ring, R, secured to theflanged top of the mortar.

I prefer to use a packing-ring, 9, of suitable yielding material,between the ring R and flanged top of the mortar, and a similarpacking-ring, 10, between the upper edge of the lining and the ring, themetal in both cases being recessed to receive the packing.

Both the anvil and sides of the mortar soon become worn by theviolentaction of the stamp; hence the advisability of a detachablelining and anvil, the former of which can be readily removed after thewithdrawal of the ring R. The anvil,however, is liable to becomejammedin its place; but it can be easily dislodged by a wedge-like tool driventhrough an orifice, c,

which I make in the mortar for this purpose.

The chamber L above referred to is formed by a perforated casing, S,secured to the ring R, and provided with a cover, S, having a centralopening, 10, through which passes thelower end of the stamp-rod O. Thisopening to is closed partly by the stamp-rod, partly by a ring, to, onthe same, and partly by a flexible ring, y, of canvas or other availablematerial, the inner edge of the ring y being attached to a flange on thering 20 and the outer edge to the cover S of the casing, or to anyavailable part of the same. The inner edge ofthe flexible ring might besecured directly to a flange on the stamp-rod but, preferrin gthatthelatter should be at liberty to turn, I make the ring 10 in two parts,so that it can be readily adjusted to its place between two collars onthe stamp-rod and then bolted together, after which the canvas ringmaybe applied. It should be understood that the ring to is fitted looselyto The mineral or other material to be crushed is introduced intothechamber L through the inlet-pipe 4, to the lower end of which ispivoted a valve, 5, the latter being connected by a link, 6, to theshort arm of the weighted lever 7, pivoted to a stand on the cover S. To

the top of this cover S is secured the annular box 8, the continuity ofwhich, as shown in Fig. 3, is interrupted to afford room for thepulverized mineral.

The canvas ring 3 is of sufficient extent to permit the rising andfalling of the stamp to the required distance.

In some cases the pulverizing may take place without .the introductionof air into or its discharge from the mortar, the material beingsimplycon fin ed in the said mortar until reduced to the desiredcondition, provision being made for the removal of the'pulverized mass;but in most cases the plan above described of withdrawing the powderwill be adopted.

I claim as my invention- 8, communicating with the interior of theeasing, and having an outlet, M, all substantially as set forth.

4. The combination of the mortar, the easing, the deflector, and box 8,communicating with the interior of the casing, and having an outlet, M,all substantially as specified.

5. The combination of the mortar L, anvil Q, lining Q, and ring R,substantially as specified.

6. The combination of the mortar, anvil,lining, and ring R withpacking-rings 9 and 10, as set forth.

In testimony whereofl have signed my name to this specification in thepresence of two subscribing witnesses.
